GRAIN-SHOCKING MACHlNE.

.This-inyentlon relates to grain-shocking machines, p g The objectsofthe in'ventiofi areto improve and simplify, the .bonstruction -of suchmachines; furthermore, to increase their efficiency in operation and'todecrease the ex- ,pense attending theirmanufacture.

With the foregoing, and other objects in -.-view, which will appear'asthejdescription proceeds, the invention resides in the c0mbi- "nationand arrangemnet of parts aud in,

the details 0L construction hereinaftef de scribed and claimed, it beingunderstood that changes in' the precise embodiment of inven' -tionherein disclosed can be made within the I scope of the following claimswithout departing fromthe spiritof the invention or sacriand 10 aredetail views.

Like reference-numerals indicate I corresponding parts inthe differentfigures of the drawings.

The shocking-machine of the present invention is constructed with anysuitable form of framework or platformA, which is i supported by meansof alarge ground wheel 1 and a small carrying-wheel 2. The platform. Aof the machine along one side thereof is secured to a binding-machine inan suitable manner, such as by means of the rackets (Shownin Fig.2. Theground-wheel 1 is journaled in a rectangular frame 4, which is mountedfor vertical sliding movement in a slightly larger rectangular frame '5,the lower ends of which are provided with flanges 6, bolted or otherwisesuitably securedv v Specification or Letters Patent.

to the platform A. The stationary frame 5 has formed in its sidesvertical slots'7, as

:shown in Fig. 1, to receive bolts 8,; which-are secured to the slidableframe4 i'reany suitable manner. For the purpose of permittingiyieldingupward movement of the frame 4 jand ground-wheel 1 with respectto the frame [53 oil-spring 9 is interposed between the upper end of.the framed and the frame 5. Rigidly secured -to the upper end of theslid- Manama-4 and extending loosely upward through the frame 5 is abolt 10, which passes through the center-of the coil-spring 9 and isprovided at its upper end with an adj ustingnut 11.. By tightening thenut 11 the frame 4 will be drawn positively upward in the frame 5', andsaid bolt lO'will limit thedownward movement of the frame 4 without.pre-

{venting the coil-spring 9 .from permitting an upward yielding movementthereof whenever the wheel '1. strikes an obstruction. It will beobvious, therefore, that by tightening the nut 11' the platform A can bedrawn downward closer to the ground whenever desired.

Thernnveying meansfor receiving a sheaf of grain'fioirr the binder andcarrying the same into the shocking-chamber, to be here inafterdescribed, preferably consists of a pair of endless aprons o; belts 1213, which are slightly inclined from the vertical, as

shown in Fig. 1, andareadapted to form between them a channel 14, alongwhich'the sheaf of grain is carried, it being understood that the sheafis fed from the binder in such manner that'it will enter the channel'14:

in an approximately vertical position with the heads of the grainupward. The means 7 for-operating the endless aprons 12'and 13 so thattheir inner portions will travel inthe same direction preferablyconsists of'a sprocketchain 15, which is suitably connected with thevertical shafts of the belts 12 and. 13.

The s rocket-chain 15' is operated by means of a s aft 16, journaled ina bracket 17 upon the platform A. (See Fig. 1.) The shaft 16 is providedwith a bevel-gear 18, which is operated by means of a bevelgear 19, saidbevehgear 19 in turn being rotated by a sprocket-chain 20. Thesprocket-chain 20.

' a rotary member B, comprising a,vertic ali shaft 29, to the lower endof which is secured a plurality of radial"blades ,30, said blades beingpreferably 'connected'with'the shaft 29 by means 'of spring brackets orarms '31. In the embodiment of invention illustrated four radial blades30, areemployed; so as to divide the shocking-chamber 28 into four eachcompartment formed by the blades sections or compartments, although. itis to be understood that a; greater or, lesser number of blades 30 canbe employed Each of the compartments formed by the radial blades 30 inthe shocking-chamber 28in the present instance is intended'to hold threesheaves of grain,--so that a shock when formed will; containtwelvesheaves of. grain. As

willhold' only three sheaves of grain, it will be apparent that therotary member, con sisting of said radial blades, must be rotated onestep each time three sheaves of grain have been fed to theshocking-chamberpso,

A T that an empty compartment will be disposed s5 pp osite the door 27.A v ,he means for-operating the rotary mem- 'ber in the shocking-1chamber 28 each time three sheaves of grain have been fed to saidchamber preferably comprises the following.

o mechanism: Journaled iii bearin -plz ites 32 u on stationarysupporting mem ers at t e upper-ends of the endless belts 12 and 13; v

I as shown in Figs. 1 and-,2, is arock-shaft'34,

which is provi de'd with a rigid depending arm 35,-the-lower end ofwhich is broadened, as shown at 3,6, and is located in the channel 14between the endless belts 12 and 13',so that each time a sheaf passesalong the channel 14 its u per end will engagethelower end of the rigidarm 35"and rocktheQshaft 34. Extending upward from the shaft 34 isarigid arm 37, with the upper end 'ofwhich is connected a flexibleelement 38, that extends upward and is connected with a lever 39,loosely fulcrumed upon a stud shaft 40, which i%suitably journaled in' asupporting:- frame 41-. The lever 39-at its free end is normally drawnnpward into raised, osition by means of recoil-spring 42. It wil beunderstood that each timea sheaf of grain moves theahgh the channel 14arid operates the arm 35 the iever 39 will be drawn downward-"againstthe tension of the s ring 42,

and after the sheaf has passed out 0 contact with the arm 35 the spring42 serves to restore said arm to roper position to be engaged by thenext sheaf.

Rigidly mounted upon-the, stud-shaft 40 is a disk 43, having threeratchet-teeth or cam members 44, which are so arranged that each timethe-lever'39 is moved downward by a sheaf of grain it will engage one ofthe cam members 44 and vwill rotate the disk 43, and

consequently the-shaft 40,"one step, after.

which the spring. 42 will draw the lever 39 upward into position 'toengageflthe next cam member, it beingunderstood 'that'the loose mountingof said lever upon; the stud-i shaft 40permits it to ride upward overthe.

inclined faces of the cam members 44 and that the.spring 42 draws it inbehind each cam member,"so as to engage the same on its downwardmovement. Rigidl. with the stud-shaft40onthe si e of thesupporting-frame 41 op.posite' the disk 43 is a connected. c

ratchet-wheel 45, with which cooperates a 'pawl. 46, mounted uponthesupportingframe 41. The ratchetrwheel ifi is provided with an;eccentrically-mounted pin-47., which duringeach rotation-of theratchetrwheel45 is adapted to engage and rock eleven 48, fulcrumed atits upper end 49-loosely$upon a shaft 50, which is journale'd in thesupporting frame 41, as shown. The lever. 48'is drawn normally to theright in Fig. 1 by means of a coil-spring 51, so thatit. will be heldyieldingly in con'tactwithth'e eccentric-pin 47 on the ratchetwheel '45.Atits lower end the lever 48 is connected witha'link 52, which issuitably secured'to a-bell-crank lever 53, .ful crumed upon a bracket.54, Thebell-c'rank lever 53 is bifurcated, as indicated at' fgi Fig. 2,and is engagedyby a; clutch mem.- ber 56,- splined upon' themain shaft21 Loosely mounted :uponthe mainshaft 21, a d+ jacent the, slidableclutch156, isa clutch 57;

When the lever 48 is operatedby the-eccentric+pin 47 on the ratchet '45,the bell-crank lever 53is rocked,.so as to throw the splined clutchmember, 56 into engagementv with the ,l'oose lutch member 57,andthus-cause said v member "57 to rotate withvthe Inainshaft- 21;.

Secured/upon the looseq clutch memberr57 is, an. eccentric disk, 58which when the clutchmember ,57 is rotated by the shaft "21 is ad a'ptedto contact with and rock to theleft in F 1 a lever; 59 which isjournaled'at itsg lower end 60 'upona fulcruml-plate 61 upon theplatform-A. p The lever 59 at its upper endis connected with a link-"rod62, having on the rear, end

thereof a hookportion 63, whicl1 is adapted to engage one of the-teethof a ratchet-wheel 64, mounted rigidly upon the shaft 2901? the It willbe obviouszthat when the splined clutch member 56 is thrown rotarymember B.

into engagement with the loose clutch memher 57 andhhe eccentric 58-isrotated to rock, the lever 591the linli'62 wilt bedrawn to thethus movethe rotary member B, as described. I

F or the purpose of moving the link-rod 62 to the right in Fig. 1 afterit has operated the rotary member B, so that the portion 63 of said.linlerod will be in position to engage the next tooth of theratchet-wheel. 64, the lower end of the lever 59 is formed with anupwardly-extending crank portion 65, which fits over a fiat spring 66,as shown in Figs. 1 and 2. The u ward pressure of the spring 66 on thecran; portion 65 of. the lever 59 throws said lever 59, and consequentlythe link-rod 62, to the right in Fig. 1 as soon asa sheaf of grain byrocking the arm in the channel 14 has stopped the further rotation ofthe member B by moving the eccentricpin 47 away from the lever 48, andthus permitting the spring 51 to pull said lever 48 to the-right in iig. 1, whereby the'bell-c'rank lever 53 is caused to disengage theclutch member 56 from the clutch member 57.

As previously intimated, each time twelve sheaves of grain have passedthrough the channel 14 between the conveyors 12 and 13 the rotarymemberB will have been given four movements and will have made one completerevolution, so that the shocking chamber 28 will be filled with twelvesheaves of grain. At this time it is desired that the rotary member Bshall be moved bodily upward within the shocking-chamber and thatsimultaneously a rearwardly and upwardly swinging door connected withthe shocking chamber and a pair of sliding doors forming the bottom ofsaid shocking-chamber shall be opened, so that the shock, consisting ofthe twelve sheaves of grain, shall be permitted to drop downward out ofthe shock ing-chamber 28 and to be left in proper position upon theground.

The means for movingthe rotary member B upward when the shocking-chamber28 is filled-will now be described. Splined upon the shaft 29 of therotary member B is a gearwheel 67, which is in mesh with a similargear-wheel 68, journaled upon a bracket 69, which is supported upon acrosspioce 70, held in proper position upon. the supporting frame 41 bymeans of adjustable collars 71. It will be understood that each time therotary member B has made one complete revolution each of the gear-wheels67 and 68 will also have made one complete revolution. The gear-wheel 68on its upper surface is provided at one point with a projection 72,

which is adapted once in every revolution of saidrgear-wheel 68 to wipeunder and rock a lever 73, fulcrumed at 74 apon a supportingarm 75,connected with the frame 41. At its upper end the lever 73 is pivotallyconnected with a smaller lever 76, fulcrumed at-7 7 upon.

the supporting-frame 41 and connected at its upper end with a clutchmember 78, which is splined upon the shaft 50. Loosely mounted upon theshaft 50 is a clutch member 79, which is rotated in a continuous mannerby means of a sprocket-chain in gear with the 8 main shaft 21, which, asbefore explained, is continuously rotated-from the ground-wheel '1. Eachtime the rotary member B and consequently the gear-wheels 67 and 68 makeone complete revolution, so as to rock the lever. 73, the splined clutchmember 78 is thrown into engagement with the loose clutch member79, sothat the shaft 50 is caused to be rotated by the clutch member 79.Mounted rigidly upon the'shaft 50 is a large cam 81, which, as shown inFig. 4, is disposed between a pair of idle wheels 82, journaled onstud-shafts 83 within a vertically-movable yoke 84, which is slotted at85 for the passage of the shaft 50. Theyoke 84 29 of the rotary memberB. It will be apparent that at the end of each complete revolution ofthe rotary member B when" the has a swivel connection at 86 with theshaft clutch member 78'isthrown into engagement with the clutch member79, as described, and

the shaft 50 is rotated the cam 81 will raise the yoke 84, which in turnwill raise the rotary member B, so as to draw the blades 30 upward outof engagement with the shock in the shocking-chamber 28 At the momentthat the rotary member B is raised in the manner described it isproposed to open the sliding doors, which formthe bottom of theshocking-chamber 28, and also to open the swinging door, which forms therear end of said shocking-chamber, so that the shock can drop to theground and the machine can move forward, so as to leave the shock inproper position.

The construction and arrangement of the rear and bottom doors of theshocking-chamber 28 and the means for opening said doors when the rotarymember B israised will now be described. The reference-numeral 87indicates a swinging door, which is p'ivotally mounted at 88 upon therear end of the shocking-chamber 28. The door 87 is provided at itslower end with a heavy counter;

weight 89 and at its upper end with a rigid upwardly-extending arm 90.Secured to the arm 90' is a flexible element 91, which is wrappedarounda drum 92 fastened uponan auxiliary shaft 93, which is journaledin uprights194 upon the platform A. The auxiliary shaft 93, as shown inFig. 2, at the end thereof opposite the drum 92 is provided with asecond rigid drum 95, around which issame from the drum 92.

wrapped a flexible element 96, which, as

shown in Fig. 3, extends downward through- 'The doors 101 and 103 areadapted to slide back and forth inguideways 104, so as to open and closethe lower end of the shocking chamber 28. Connected with each of thesliding doors '101 and 103 and with each of the arms 100 and 102 is apair of coil-springs 105, the tendency of which is .to draw the doors101 and 103 into opened positionand away from each other. The wei ht 89upon the swinging-door 87 of the shoc ing-chamber 28 is sufficientlyheavy to swing said door 87 into closed position, thus drawing upon theflexible element 91 and unwinding the As the flexible element 91 isunwoundfrom the drum 92 by the weight 89 the flexible element .96is'wound upon the drum 95, thus drawing the sliding Wlll be understood,there doors 101 and 103 into closed position against the tension of thesprings 105. It ore, that the -weight 89 serves not only automaticallyto hold the swinging door 87 in closed position, but also the slidingdoors 101 and .103.

For the pu ose of opening the swinging door 87 and t e sliding. doors101 and 103 when the rotary member B is. raised the following mechanismis employed: Rigidly secured at 106 to the yoke 84, as shopvn in Figs. 1and 2, is a depending arm 107, which, as shown in- Fig. 5, is providedat its lower end with a latch 108, fulcrumed at 109 and having arearwardly-extending arm 11.0 and 4, pin 11.12, mounted on the arm 107.-As the a slot 111, through which extends a limiting,-

arm 107 moves upward with the yoke 84 the face '1 13 of the latch'108engages and rocks a lever 114,{,WhlOh lS fulcrumed at 115 upon asupportingmrm 116, secured at 117 to the cross-piece of the frame. Asthe lever 114 is rocked upward at its rear end by the latch i 108 theforward end of said lever pushes downward upon a link-rod 118, which ispiv v ."otally connected with the lever 1 14, as shown at 1 19. Securedto the lower end ofthe link rod 118, as shown in Fig. 2, is a bifurcatedwedge member 120, which straddles the shaft 93 betweena fixed collar 121and a clutch member 122, which. is splined on said shaft '93. As thewedge member 120 is forced d'ownward by the rod- 1 18 it pushes theclutch member 122 intoeng'agement with a clutch member 123-, which isloosely mounted on the shaft 93 and is continuously rotated by meansOra. sprocket ehain 1 24 fromthe con tinuousl-ywotated main shaft 21. Itwill be obvious, therefore, that as the yoke-84 is raised, in themannerdescribed to elevate the rotary memb r the wedge 120 is movedengagementwith the ,clutch: 123, whereby the shaft. 93 is rotated in such manneras to wind the flexible element 91 upon-the drum 92, so as to open therear door 87 and at the same time to pay-off the flexible elementv 96from thedrum 95, so as to permit the springs 105 to exert theirinfluence to open the slidingdoo rs 101 and 103. As the operations ofraising the rotary member B and opening the swinging door 87 and thesliding doors 101 and 103 take place simultaneously, it will bedownward, so as to throw the clutch 122 into obvious that theshock,consisting of the twelve sheaves in the shocking-chamber 28, will bedropped, to the ground when the sliding ddors at the bottom of saidchamber are entirely opened and that the swinging door 87 b'yreas'on ofthe fact that it has been raised into opened position will clear theupper end of the shock. ,When the yoke 84 has reached its highestposition, the arm 110 of the latch 108 comes into contact with a 'rigidsto member 125-, which is secured to the mac inc-frame in any suitablemanner and is formed with'a bent end 126. The engagement of the" arm 110with the bent =por-' tion 126 of the stop member 125 serves-to trip thelatch 108 out of engagement with the lever 114. Said lever 114 is thenimmediately drawn downward into its lowermost position by a weight 127,which'is secured to said lever, asshown in Fig. 1. The downward.movement of the lever 11.4 draws-the wedge upward, so as to release theclutch member 12 2 from the clutch member 123,

thus stopping the rotation of the shaft 93 8 while the door 87 is inraised position and the doors 101 and -103 arein openedposition.v

The weight 89 on the door 87 then causes said door to move downward toclosed position, thus rotating the shaft 93 through the flexible element.91 andeausing th e flexible element 96 to draw thesliding doors 101 and103 into. closed position againsttlie action of the springs 105.

As previously explained, it is proposed thatthe lever 73 in Fig. 2 shallbe employed for throwing the shaft 50 into operation to raise and lowerthe rotary member 13 when the shocking-chamber 28 contains twelvesheaves of grain. It may be here explained lution each time. threesheaves of grain have been fed to the shocking-chamber.- After the lastthree sheaves have beenfed to the that the gear-wheel-68 makes aquarter-revo shocking-chamber the gear-wheel .68 makes the last quarterof its revolution and during this last movement the projection 72 firstrocks the lever 73, so. as to throw the clutches, 7 8 and 79. intoengagement with eachother' and hold the same in said engagement un 11the shaft 50 has made one complete revolutiongthereby raising andlowering therotary member 3. The projection 72 then slips fr'emi underthe lever 73 and av spring 128 rocks said lever, so as to move" theclutches 78 and 7 9 out of engagement, with. each other. It will beunderstood, therefore, that the rotation of the clutch member 79 mustbesufficiently rapid to give the shaft 50 one complete revolution duringthe limited time that the projection 72 holds the clutches 7 8 and 79 inengagement with each other before slipping from under the lower end ofthe lever 7 3 at the end of the last quarter-revolution of thegear-wheel 68. v

The reference-numeral 129 in Fig. 3 indicates a portion of a binderto-which the brackets 3 are secured, and the referencenumeral 130indicates a brace-rod which is secured to the outer forward corner ofthe shocking-machine and extends inward, so as to be connected with somesuitable portion of the binder. I

The improved shocking-maclfine of the present invention is strong,simple, durable, and inexpensive in construction as well as thoroughlyefficient in operation. The ro-' tary member Biserves to hold thedifferent sheaves in proper position in the shocking chamber 28 to forma shock, and the frustoconical sha e of the shocking-chamber28 serves toho d the upper end of the shock in contracted position. Furthermore, Ias the doors 101 and 103 are drawn apart to permit the shock to falloutof the shocking-cham- I her they serve to draw apart the lower endsof the shock, so as to give the same a' broad base, and thus hold it inproper position upon the ground.
